Neither. It's because Collin Campbell's a moron who can't level consistancy within the NHL's rules.
THey want to eliminate head hits and make players more responsible. I disagree that Bertuzzi's hit looked like his arm just came up from momentum... he's a tall guy, and could've easily not done what he did. He should've been fined. Campbell did the same lame **** with the Islanders and others... He's handed down a fine to Matt Cooke that nobody in Pittsburgh disagreed with. But he's been inconsistant with everything else, all year, and he's a detriment to their attempt to end head hits in the league.
Till they get tough, and actually levy things heavy-handed to everyone instead of being selective about it, they're pathetic and hurt the league.
I completely felt Bertuzzi's hit was BS, avoidable, and he's a repeat offender... he got a pass for some reason. Oh well. Another day in the NHL, where the ref's may decide to call the game the way it should be, or put their whistles away and let everyone enjoy a rugby game on ice.
